Low Testosterone??

My boyfriends libido has been CRAZY since he started his antidepressants...

The only problem is that he's taking like 45 min to orgasm now. It gets soft off and on and I have to use my mouth and hands to finish him off, which still takes forever. He's really frustrated about it and his dr is dodging the question and simply insisting that it doesn't matter if it's the meds- he needs them. He's the only dr he can see with our insurance so we're kind of at a loss. Any advice? I saw some testosterone supplements at the pharmacy and considerred suggesting them? Has this ever happened to you?
